• 1 other identifier: 1372621
• Study Type: interventional
• Target: 150
• Locations: 1 country
• Sites: 1

Brief Summary

This is a prospective clinical study involving up to 150 subjects with localized prostate cancer who are scheduled for radiation treatment with rectal spacer placement. The goal of this clinical trial is to assess the safety and efficacy of perirectal spacers in patients undergoing radiation therapy for the treatment of localized prostate cancer. Study visits:

• Screening
• Spacer placement
• Treatment planning simulation
• End of the radiation treatment
• 1, 3, 6, 12, 18 and 24-months FU visits.

BioProtect Balloon Implant System

EXPERIMENTAL

The Bio Protect Balloon Implant System (BioProtectLtd.,TzurYigal,Israel) is an Food and Drug Administration approved rectal spacer that consists of a solid biodegradable balloon-shaped material composed of poly L-Lactide-co-caprolactone

Device: BioProtect Balloon Implant™ System

Interventions

BioProtect Balloon Implant™ System DEVICE

The BioProtect Balloon Implant System is intended to temporarily position the anterior rectal wall away from the prostate during radiotherapy for prostate cancer, and by creating this space, to reduce the radiation dose delivered to the anterior rectum. The balloon is inserted into the perirectal space and inflated to its pre-defined size. The Balloon is made of biodegradable materials that maintain the space for the entire course of prostate radiation treatment and are absorbed by the patient's body over time
